Solution: Aluminum has 13 electrons so it will have the electron arrangement (2, 8, 3) which represents two electrons in the n=1 energy level, eight electrons in the n=2 level, and three electrons in the n=3 level. Transport of thermal energy in solids may be generally due to two effects: Copyright 2021 Periodic Table | All Rights Reserved |. You must recognize that the second principal energy level consists of both the 2 s and the 2 p sublevels and so the answer is three. From the hydrogen atom energy levels, we would have expected that all \(n = 2\) electrons would have the same Below is a table showing the maximum number of electrons an element can have for each of its energy level shells. Aluminum has four energy levels, and gallium has three energy levels. When this shell is full the electrons begin to occupy the next energy level. boron (B), aluminum (Al), gallium (Ga) If boron has two energy levels, then how many energy levels do the other two elements have?
